From 1b2b32dcdb3df28dd103033c73cac2417fa05845 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 24 Sep 2014 08:38:44 -0400 Subject: [PATCH] locks: fix fcntl_setlease/getlease return when !CONFIG_FILE_LOCKING Currently they both just return 0. Fix them to return more appropriate values instead. For better or worse, most places in the kernel return -EINVAL when leases aren't available. -ENOLCK would probably have been better, but let's follow suit here in the case of F_SETLEASE. In the F_GETLEASE case, just return F_UNLCK since we know that no lease will have been set.
